Abstract
Abstract A device for relieving skin itch includes a flexible mesh sheet having a pair of spaced bare electrical wires interleaved within the sheet. An electrically non-conductive cover sheet is applied to one side of the mesh sheet while portions of the electrode wires are exposed on the other side of mesh sheet for contact application to the skin to relieve itching when a voltage is applied to the terminal ends of the electrode wires. The mesh sheet may be stored in a roll and cut to any desired length appropriate to the skin area to be treated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
An electrode apparatus for contacting a human body comprising: a planar flexible electrode assembly including a sheet of electrically non-conductive mesh-like material, first and second flexible electrically conductive wires incorporated into said mesh sheet along the length thereof in a spaced relationship through the interstitial spaces of said mesh sheet, a flexible planar cover sheet of electrically non-conductive material secured to one side of said mesh sheet, one of the terminal ends of each of said first and second wires being adaptable for selective connection to a source of electrical power at one end of the length of said mesh sheet, the other terminal ends of said first and second wires terminating at the other end of the length of said mesh sheet; the other side of said mesh sheet being adapted for contact application to a selected skin area of the human body.
Claim 2
Dependent Claim
144 words
An electrode apparatus for contacting a human body comprising: a planar flexible electrode assembly including a sheet of electrically non-conductive mesh-like material, first and second flexible electrically conductive wires incorporated into said mesh sheet along the length thereof in a spaced relationship through the interstitial spaces of said mesh sheet, a flexible planar cover sheet of electrically non-conductive material secured to one side of said mesh sheet, one of the terminal ends of each of said first and second wires being adaptable for selective connection to a source of electrical power at one end of the length of said mesh sheet, the other terminal ends of said first and second wires terminating at the other end of the length of said mesh sheet; the other side of said mesh sheet being adapted for contact application to a selected skin area of the human body.
Claim 3
Dependent Claim
46 words
An electrode apparatus as defined in claim 1 wherein at least a portion of the lengths of each of said electrically conductive wires protrudes through said other side of said mesh sheet for contact with said selected skin area when said mesh sheet is applied thereto.
Claim 4
Dependent Claim
25 words
An electrode apparatus as defined in claim 1 wherein said mesh sheet is flexible for conforming application to the contour of said selected skin area.
Claim 5
Dependent Claim
16 words
An electrode apparatus as defined in claim 3 wherein said mesh sheet is of textile material.
Claim 6
Dependent Claim
36 words
An electrode apparatus as defined in claim 1 wherein said one of the terminal ends of each of said first and second wires are located immediately adjacent one end of the length of said mesh sheet.
Claim 7
Dependent Claim
28 words
An electrode apparatus as defined in claim 1 wherein said one of the terminal ends of each of said first and second wires extend beyond said mesh sheet.
Claim 8
Dependent Claim
32 words
An electrode apparatus as defined in claim 1 wherein the portion of said wires incorporated into said mesh sheet are substantially parallel to each other in the plane of said mesh sheet.
Claim 9
Dependent Claim
31 words
An electrode apparatus as defined in claim 7 wherein said wires are of substantially wave shape configuration in the plane of said mesh sheet along the length of said mesh sheet.
Claim 10
Dependent Claim
14 words
An electrode apparatus as defined in claim 7 wherein said wires are closely spaced.
Claim 11
Dependent Claim
38 words
An electrode apparatus as defined in claim 1 wherein said mesh sheet is in strip-like configuration adaptable for storage in a rolled-up form whereby said mesh sheet incorporating said wires may be selectively cut to a suitable length.
